Technical Specifications
Architecture & System Overview
Reselling is the same item described five different ways, plus a messaging inbox that decides whether you make money on it.
The Online Reseller Stack is a 134-prompt playbook covering every marketplace you actually sell on: eBay listings, item specifics and store policy, Facebook Marketplace and local negotiation, Poshmark bundles, Depop promotion and Mercari pricing — plus the buyer chat, disclosure and pricing work that runs across all of them.
Start with the Inventory Primer — paste in what you sell, which platforms you list on and what you pay to source — and every prompt after it works for your actual stock.
The cross-posting prompts rewrite one item for each marketplace's search behaviour rather than pasting the same title into five boxes, because what ranks on eBay is not what surfaces on Depop. The negotiation scripts cover the moments that cost real money: the lowball, the hold request, the no-show, and the buyer who tries to renegotiate once they are standing in front of you.

Verified User Feedback
Cross-posting rewriter is the whole thing for me
I list the same items on eBay, Poshmark and Mercari and used to paste the same title everywhere. Having it rewritten per platform, with the ranking field called out, has noticeably changed what gets seen.
The no-show and renegotiation scripts
Marketplace buyers trying to knock fifty off when they turn up was costing me constantly. Having an actual line ready, and a walk-away point decided in advance, has stopped it twice already.
Flaw disclosure prompts ended my dispute problem
I was getting not-as-described cases on used items. The disclosure prompt forces you to list every flaw and phrase it plainly. Three months, no cases.
Depop section is the thinnest
eBay and Marketplace coverage is deep and genuinely useful. Depop gets eight prompts and feels lighter than the rest. Still good value overall given how much of the rest I use.
Frequently Asked Questions
How is this different from the separate systems you used to sell?
It is all of them, in one purchase. eBay Listing Title & Description, eBay Item Specifics & Policy Builder, eBay Buyer Message & Offer System, eBay Store About & Policy Copy, eBay Seasonal Listing Refresh Plan, Facebook Marketplace Listing System, Facebook Marketplace Buyer Chat Script, Facebook Marketplace Negotiation Plan, Poshmark Listing & Bundle System, Depop Listing & Promotion Plan, Mercari Listing & Pricing System are now sections inside this toolkit. Bought individually they came to $388.
I only sell on one platform. Is most of this wasted?
No, but be realistic about what you are buying. Roughly half the toolkit — titles, item specifics, disclosure, buyer messages, pricing, aged inventory — applies to any marketplace. The platform-specific sections for the ones you do not use will sit unread.
Does this help with sourcing, or only selling?
Selling. The pricing prompts cover reading comparable sold listings and setting markdown ladders, which informs what an item is worth paying for, but there is no sourcing or inventory-acquisition section.
How is it delivered?
You receive a PDF with all 134 prompts organized into 11 sections, delivered within 24 hours of purchase. No app or account required — copy a prompt, fill in the bracketed variables, and paste it into ChatGPT, Claude, or Gemini.
Can I use this for client work?
Yes. Your purchase includes a single-user commercial and personal license, so you can use every prompt in your own business or for client deliverables without restriction.
